Wish I could. I don't know how I do it myself . . . me, the Aspie who doesn't understand social cues and body language
But I've been told, the temperature in the room usually drops about about 10 degrees F when I use "the stare."
Yeah, when my co-workers see that look on my face they know something has gone sideways and they're all desperately hoping that it wasn't one of them that did whatever it is I'm steamed about. I've got one poor guy so freaked out he jumps whenever he hears my voice, and I've never pointed the stare at HIM.
I have large, heterochromic eyes and the stare involves extended periods of not blinking. This unnerves people to an extreme degree, sometimes. Hey, when you're short, you use the weapons you have to make people respect you.
